Why choose expert custom backend development
Data driven results from real projects.
IRPR has delivered 200+ backend systems across 50 countries. Our average project timeline is 12 weeks from kickoff to deployment. Systems we build achieve 99.9% uptime with automated monitoring.
We use a fixed-price model starting at $80K for a full-featured MVP. No hourly billing means predictable costs and no scope creep.
IRPR vs Generic Dev Shops
The wrong partner costs time and money. See the difference.
Many agencies build backends with unclear requirements, hourly billing, and no handover plan. IRPR delivers a fixed-price roadmap, full code ownership, and modern infrastructure.
Our senior engineers (10+ years experience) architect systems that scale from zero to millions of users. We include deployment scripts, monitoring, and documentation.
- No fixed scope or price upfront
- Junior developers working across multiple projects
- You pay for every hour including meetings
- Code is delivered without tests or documentation
- No ownership transfer until final payment
- Post-launch support requires new contract
- Fixed-price quote after a 2-week Roadmap phase
- Senior engineers (10+ years) dedicated to your project
- No hourly billing — you know the total cost from day one
- Source code, tests, and docs delivered in your own repo
- Full IP ownership immediately upon payment
- 30-day post-launch support included
Our Backend Development Process
Four phases from idea to deployment.
We follow a structured approach that eliminates guesswork. Each phase produces a clear deliverable so you know exactly what ships and when.
All phases are included in the fixed price. No surprises.
What ships with your backend
Every deliverable is documented and handed over.
You get everything needed to run and extend your backend independently. No hidden gaps.
- Full source code in your GitHub or GitLab repo
- CI/CD pipeline using GitHub Actions or GitLab CI
- Comprehensive API documentation (OpenAPI / Swagger)
- Unit and integration tests with coverage reports
- Deployment scripts for AWS, GCP, or Azure
- Health checks and monitoring setup (Sentry, Datadog)
- Database schema migrations and seed data
- Security audit report from automated tools
What we ship in this practice.
SaaS Subscription Billing Backend
Built a microservice architecture using Node.js, PostgreSQL, and Stripe that handles 10,000+ concurrent subscriptions. Reduced billing errors by 95% and enabled automated dunning.
Real-Time Fintech Data Pipeline
Developed a Kafka-based stream processing system in Go that processes 1 million transactions per day with sub-50ms latency. Met PCI-DSS compliance.
HIPAA-Compliant Patient Portal Backend
Created a HIPAA-compliant API using Python/Django and PostgreSQL for a telemedicine startup. Handled 100,000 monthly patient records with audit logging.
Ecommerce Marketplace Order Engine
Built an order orchestration system with Node.js, Redis, and RabbitMQ that coordinates 5,000 orders per hour across 200 vendors. Reduced manual intervention by 80%.
Enterprise SSO and User Management API
Implemented OAuth 2.0 SSO using Auth0 and a custom user service for a 10,000-employee company. Cut login support tickets by 60%.
Real-Time Gaming Leaderboard Backend
Designed a WebSocket-based leaderboard service using Go and Redis that supports 50,000 concurrent players with 100ms update latency. Used for a mobile game.
Why teams hire us.
Fixed Price from Day One
We quote a fixed price after a 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. Our average backend project costs $80K-$250K.
Senior Engineers Only
Every project is staffed with engineers who have 10+ years of experience. No outsourcing to junior devs. You work directly with the team building your system.
Full Code Ownership
All source code, documentation, and IP belong to you. We deliver the code in your git repository from sprint one. No lock in, no licensing fees.
Compliance Built In
We design backends to meet HIPAA, PCI-DSS, and SOC 2 standards from the start. Our infrastructure uses encrypted connections, audit logs, and role-based access.
Modern Tech Stack
We use Node.js, Go, Python, PostgreSQL, Redis, Kafka, Docker, and Kubernetes. You get a modern stack that attracts top engineering talent for your future hires.
30-Day Post-Launch Support
After deployment, we provide 30 days of monitoring support. We fix any issues and ensure your team can operate the system independently.
